add a check for block overlap after the command line parsing
* Algorithm
*
* In a inner loop, the parameters from SSET are translated into temporary
* variables so that 1 row is printed at a time (getting the coordinate indices
* at each row).
* We define the stride, count and block to be 1 in the row dimension to achieve
* this and advance until all points are printed.
* An outer loop for cases where dimensionality is greater than 2D is made.
* In each iteration, the 2D block is displayed in the inner loop. The remaining
* slower dimensions above the first 2 are incremented one at a time in the outer loop
*
* The element position is obtained from the matrix according to:
* Given an index I(z,y,x) its position from the beginning of an array
* of sizes A(size_z, size_y,size_x) is given by
* Position of I(z,y,x) = index_z * size_y * size_x
* + index_y * size_x
* + index_x
*
tested: windows, linux
New version of the function h5tools_dump_simple_subset, to display subsetting. The new algorithm is:
Introduced an outer loop for cases where dimensionality is greater
than 2D. In each iteration a 2D block is displayed by rows in a inner
loop. The remainning slower dimensions above the first 2 are incremented
one at a time in the outer loop
Note: when blocks are introduced, the display is not correct. This is a bug that requires an improvement of the algorithm.
Fix several bugs
1) the parsing of subsetting was using atoi to convert the parameter to an int, which caused problems for numbers greater that int. Substitute with atof
2) the printing of indices in the subsetting case was not being done. Solution: calculate the element position at the start of the subsetting using the algorythm
Given an index I(z,y,x) its position from the beginning of an array of sizes A(size_z, size_y,size_x) is given by
Position of I(z,y,x) = index_z * size_y * size_x
+ index_y * size_x
+ index_x
And pass that position to the function that dumps data, h5tools_dump_simple_data.
3) several index counters were declared as int, use hsize_t instead
4) modified the test generation program so that it includes test cases for subsetting of 1d, 2d, 3d, and 4d arrays and add these tests to the shell script
